LOCKING BAND FOR CONTAINERS Filed April 16, 1958 NVENTOR HARRY Scorr A TTD/@VE YS United States Patent O 3,054,548 LOCKING BAND FOR CGNTAINERS Harry A. Scott, Van Wert, Ohio, assiwor to Continental Can Company, Inc., New York, N.Y., a corporation of New York Filed Apr. 16, 1958, Ser. No. 728,945 Claims. (Cl. 229-5.7)

This invention relates to an improved locking band especially adapted for use on ber containers having an upper metal chime -upon which a cover will be removably secured.

A locking band of the character involved is disclosed in United States Letters Patent 2,579,975, issued to Harry A. Scott et al. on December 25, 1951. However, although this disclosed band functions to retain the cover on the container, it has been found that it may have relative rotation on the chime of the container upon which it is mounted. This relative movement is especially undesirable when a workman attempts to relocate a filled drum during loading or unloading on freight cars, trucks or loading platforms where he tilts the drum on its lower edge and by grasping the locking band attempts to roll the drum on said lower edge. Due to the free rotation of the band, the workman Will only rotate the band on the chime and the drum cannot be readily rolled in this manner. Various factors result in the loose tit of the locking band on Vthe drum, for example, variations in materials used in manufacture, -wear and inaccuracies in forming dies, etc.

A primary -object of this invention is to provide an improved locking band for retaining a cover on a container, the band including means preventing relative rotation of the band on the container with which it is used.

Another object of this invention is to provide an improved split-type locking band including a peripheral skirt n on the container whereby rotation of the band on the container is prevented.

A further object is to provide a novel locking band and container chime arrangement of the character stated wherein the peripheral skirt of the band terminates in an -edge portion which is convoluted or scalloped to present circumferentially alternated high and low points, said low points being disposed to engage the chime and be placed under compression during the securing of the locking band, whereby to secure the band against turning movement relative to the chime.

With the above and other objects in view that will hereinafter appear, the nature'of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.

Inthe drawings:

FIGURE 1 is an elevation of an upper portion of a container upon which the locking band of the invention is locked for retaining a cover thereon;

FIGURE 2 is an enlarged fragmentary section taken on line 2 2 of FIGURE 1 through a low point on the peripheral skirt of the locking band;

FIGURE 3 is an enlarged fragmentary section taken on line 3-3 of FIGURE 1 through a high point on the locking band; and

FIGURE 4 is a Vertical section of the locking band when removed from the container.

Referring to the drawing in detail an upper end portion of a cylindrical ber board container is indicated generally at 5, the container being formed from a plurality of convoluted layers of heavy paper. The conassists Patented Sept. 18, 1962 ice tainer wall 6 is formed with an inwardly turned rounded shoulder 7 continuing in a reverse bend portion 8 terminating in a vertical flange portion 9. Crimped about the upper end of the container is a reinforcing metal chime member 10 which includes a rounded shoulder 11 conforming to shoulder 7 of the container. The chime member overlies the outer surface of the reverse bend portion v8 and the vertical flange 9 of the container, terminating in a reinforcing bead portion 12 on the upper edge of the vertical flange portion 9.

Indicated generally at 13 is a portion of a removable cover which includes a circumferential downwardly directed rib 14 to be received within the container body portion S and a downwardly opening peripheral groove or channel 15 into which the bead portion 12 extends. The cover includes a downwardly directed peripheral flange -16 overlying the outer surface portion `17 of the chime member, the flange including a reverse bend lower edge portion or hem 18.

Indicated generally at 19 is a split clamping band for retaining the cover 13 on the container. The clamping band is operated by means of a lever-actuated device indicated generally at 20, complete structural details and operation of which are disclosed in detail in the before mentioned Letters Patent 2,579,975. Without going into these details, the mechanism 20 functions to expand or contract the band about the upper end of the container to permit the removal of the cover or to clamp the cover in a container closing, cover securing position.

The band 19 comprises a vertically disposed flat body portion 21 engageable against the lower edge hem portion 18 and continuing in an upper horizontal flange 22 terminating in a reverse bend or hem portion 23 engageable at 24 on the cover channel 15. Extending inwardly from the flat body portion 21 is a horizontal flange 25 engageable at 26 with the chime member. The flange 26 continues in an angularly depending skirt or flange por. tion 27 which is of an undulated or uted configuration including high points 2S and low points 29. The high points 2S will be located in a plane at a fixed angle A downwardly and outwardly from the horizontal flange 26 when the clamping band 19 is in the locked position, which, when the Acooperating parts are properly constructed, will dispose the high points 28 in close proximity to the adjacent shoulder 111 of the chime member. The low points 29 as clearly shown in FIGURE 4, will be disposed below the high points a distance x, whereby when the band is locked or clamped, said low points Will be placed under compression to engage the adjacent shoulder portion 11 of the chime member with very secure retaining friction and prevent rotation of the band and cover with relation to the chime member. Utilization of the novel clamping band will facilitate the ready movement of filled containers by tipping and rolling the same on their lower edge portions to thus overcome the shortcomings of the prior art previously referred to.

Although the expedient of an undulated, iluted or scalloped portion on the depending skirt of the clamping band for the purpose mentioned has been described in detail, expedients such as corrugations, serrations or the like are considered to be within the purview of this invention.

From the above description, it is readily apparent that the described clamping band will readily accomplish the objects and afford the advantages set forth. Various changes and modifications may be made in details of construction of the specifically described preferred embodiment without departing from the Spirit thereof, such changes being limited only by the scope of the appended claims.
